查询词典 pressure

Conditions of the seepage and stress is a dynamic process, and also shows its interaction and interdependence. Owing to the closure of the fracture, the hydraulic gradient and the permeability pressure of the fracture turn large, and also promote the expansion of water cracks, and fissures connectivity increasing. The increase of the crack opening width will result in the increase of the infiltration capacity and seepage flow, and the reduction of seepage pressure. Because of the dynamic dependence of the fracture aperture, pressure and seepage, under certain conditions, changes in fracture aperture can lead to the formation of local water-passage, and the local emission of high pressure water, and thus promotes the formation of the sudden outgush disasters.

结果表明：洞室开挖完成后，在围岩渗流与应力耦合作用下，围岩中裂隙隙宽、裂隙中水压及其渗透流量的变化是一个动态过程，且相互作用与相互依赖；裂隙的闭合使得结构面水力梯度变大，作用在裂缝上的渗透压力增大，促进导水裂缝扩展，裂隙连通性增加；裂缝张开度增大，渗透能力增强，渗流量增大，其渗流压力相应降低；由于围岩中裂隙隙宽、压力和渗流量的动态依赖性，在一定条件下，裂隙隙宽的改变可导致局部水力通道的形成，高压水头从局部涌出，从而促进突水灾害的形成。

Plastic should lower 3 steps, because plastic is a step to add meltresin material to cyclinder , Higher stick of resin material ,higher screwback pressure. Screw speed differs depending on decomposing temperatureof resin material ,Higher screw speed ,Higher trim force of resin,higher cyclinder temperature. Some resin material may decomposes so it setscrew speed in mid-speed such as 45-75%, In plastic step setting screwback pressure is very important, Higher screw back pressure ,higherquality of product screw back pressure make resin structure order, Moldingproduct is beautiful and volume stable. But ,it maybe flow if screw

再复杂的熔胶旋转过程最多不会超过三段，因为熔胶本身就是存在于把胶熔进料筒的过程，如果原料粘度大，熔胶压力则大，但速度则应取决于原料的分解温度，熔胶速度越快，原料中的剪切力则会越大，料管温度则越高，局部原料产生分解的可能性则会越大，故一般熔胶会采用中速为宜，如45%-75%，熔胶同时会碰到一个比较重要的环节，那就是背压的使用，产品精度要求越大，背压的使用则更大，背压可使原料分子间结构更紧密，成型出的产品则尺寸更稳定，外观越好。

The permanent magnets are now mouthed at the exterior of the high-pressure vessel and are no longer in contact with the fluid sample. So this construction of equipment decreases the contamination of each other. Concerning the temperature-control system, the present instrument employs one non-vibrating new technology. In the high pressure systems, a simple and fast high-pressure pump was used to generate hydraulic pressure. This equipment is more easy to control than the literature\'s methods. A digital lock-in amplifier has been used as sinusoidal current function generator and the induced signal detector.
